Mhm. When "Electric Soldier Porygon", the original 36th or 37th episode of the anime, was released in Japan, there were flashing lights in the episode that gave about 700 Japanese kids (and maybe adults, who says adults can't watch Pokémon) seizures. None died, I believe, but some were feeling nauseous and some had major headaches. The flashing lights were caused by Pikachu destroying something while Ash, Misty, Brock, Pikachu, and Porygon were in a PC or something.

Since then, Porygon, Porygon2, and Porygon-Z have never made any appearances. If you dare, watch "Electric Soldier Porygon" on YouTube. It surely didn't give me a seizure, but you should ALWAYS be careful about your health. I am NOT forcing you to watch the episode, and you probably shouldn't watch it.
